原子吸收光谱法（Atomic Absorption Spectrometry, AAS）是一种用于测定样品中特定金属元素含量的高灵敏度分析技术。其核心原理基于基态原子蒸气对特定波长光辐射的选择性吸收。以下是详细解释：
基本原理
当处于基态的原子受到特定波长的光辐射时，会吸收能量跃迁至激发态。每种元素都有其独特的吸收波长（共振线）。通过测量特定波长光被样品原子蒸气吸收的程度（吸光度），并与已知浓度的标准溶液进行比较，即可定量测定样品中该元素的含量。其定量基础遵循朗伯-比尔定律（Lambert-Beer's Law）：
$$
A = log(frac{I_0}{I}) = varepsilon b c
$$
其中，$A$ 为吸光度，$I_0$ 和 $I$ 分别为入射光和透射光强度，$varepsilon$ 为摩尔吸光系数，$b$ 为吸收光程长度，$c$ 为待测元素浓度。

原子吸收光谱法（Atomic Absorption Spectrometry，AAS）是一种用于元素定量分析的仪器分析方法，其核心原理是通过测量气态基态原子对特定波长光的吸收程度来确定样品中元素的含量。以下是详细解释：
原子吸收光谱法基于原子中电子能级跃迁的特性。当光源发出的特征辐射通过原子化后的样品蒸气时，基态原子会选择性吸收与其能级差匹配的特定波长光，导致光强度减弱。通过测量吸光度变化，可推算元素浓度。
根据朗伯-比尔定律，吸光度（A）与元素浓度（C）成正比： $$ A = KC $$ 其中，K为与实验条件相关的常数。通过标准曲线法可定量未知样品浓度。
例如，在环境监测中，流动注射氢化物原子吸收法可检测河流沉积物的砷和汞，检出限低至2ng/L，精密度和准确度均表现优异。
原子吸收光谱法通过基态原子的选择性吸光实现元素定量，兼具高灵敏度与准确性，是痕量分析的重要工具。其技术分支（如氢化物法、石墨炉法）进一步扩展了应用范围。
